A continuous thin cushion is provided with stiff backing sections, arranged to align with the sections of an underlying conventional articulated hospital bed. The combination of cushion, backing, and preexisting hospital bed has a desired composite degree of firmness, ideal for orthopedic patients with back problems. Suitable covering and attachments to the bed are provided. Inexpensive materials and methods make the unit economically disposable.
